He is best known for his large-scale sculptural portraits made from recycled cardboard and ducktape. These sculptures are often portraits of his family, friends and relatives. After his arrival in the Netherlands, Quentley discovered that many materials, such as cardboard, are used differently than in Curaçao. As explained by Quentley:“I collect cardboard boxes on the streets, which I find often in good condition. As these materials are easy to reuse, I use them for my portraits. I collect photos of friends or relatives and model the cardboard of the unfolded boxes with a Stanley knife and tape to their likeness as much as other sculptors do with chisels and stone or wood."
From the age of thirteen, Quentley received lessons in drawing, painting and making spatial installations from the center for contemporary art “Instituto Buena Bista” in Curaçao. Quentley subsequently completed his education at the Royal Academy in The Hague, from which he graduated in 2018. In the same year, he won the Best of Graduates at gallery Ron Mandos in Amsterdam. Since then, Quentley’s art has been exhibited at the Museum Beelden aan Zee in Scheveningen, Het HEM in Zaandam and Museum Rijswijk.
